#resize

Convert, resize and optimize images between JPEG, PNG, WebP, AVIF, GIF and TIFF — powered by sharp / libvips. Convert a single image to another format with control over quality and dimensions, resize with selectable fit modes, optimize (re-encode) for smaller files with a reported byte saving, and read full image metadata (format, dimensions, channels, alpha, animation, density). Send an image by public URL, base64 or a raw binary request body and receive the result as base64 JSON or, with raw=1, the raw image bytes. Only public http/https URLs are accepted and private or internal hosts are blocked. Pure server-side processing (no third-party upstream). Ideal for upload pipelines, CDNs and thumbnails, WebP/AVIF modernisation and bandwidth optimisation.
